The financial fair play takes into account the last 3 years of a football club in terms of income and expenditure. A club isn't allowed to have more than 40 mil loss for that period. So basically, Monaco have 2 years to sign some false advertising contracts, that would probably be from Rybolovlev's companies, just like city with Etihad. This gives them false income that on paper is coming from investors but is actually still the crazy dictator's spending spree.
